DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0042] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0044] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0045] In the prior art, the applicator includes a shell and a handle. The handle is arranged on the shell. The shell is a relatively sealed structure. The shell is pressed by the handle to deform the shell and break the container inside the shell. The container is generally an ampoule, which is a relatively fragile structure.

[0046] However, there are some technical problems in the prior art that need to be solved urgently. For example, in actual operation, a large pressing force is often required to break the ampoule bottle.

[0047] Please refer to Figure 1-Figure 20 In order to solve the technical problem, the present embodiment provides an applicator 10, an applicator device 100 and an applicator set 1000 which can solve the technical problem. The applicator 10, the applicator device 100 and the applicator set 1000 will be described in detail below.

[0048] Please refer to Figure 1 The application kit 1000 includes a package 200 , a container 20 and an applicator 10 , and the applicator 10 and the container 20 are both arranged in the package 200 .

[0049] Optionally, the package 200 is a transparent plastic packaging bag, ensuring that the container 20 and the applicator 10 inside the package 200 can be clearly seen without opening the packaging bag, which is convenient for inspection and confirmation. Of course, the package 200 can also use a high-barrier plastic film or composite material, such as polyethylene (PE), polypropylene (PP) or a laminated film, to ensure that the package 200 can effectively block microorganisms, moisture and other pollutants.

[0050] The package 200 in this embodiment can adopt a reliable heat-sealing process to ensure that the sealing edge is firm and has no risk of leakage, and prevent external contamination from entering. In order to open the package 200 conveniently, quickly and safely, an easy-tear opening or a pull strip is generally designed on the package 200.

[0051] Of course, the package 200 can also be a packaging box, in which the applicator 10 and the container 20 are both arranged. A cushioning material such as a foam pad and a sponge can also be arranged in the packaging box to fix the applicator 10 and the container 20 to prevent damage during transportation.

[0052] Figure 1 In the embodiment, the package 200 can contain one applicator 10 and two containers 20. Of course, in a specific implementation, the package 200 can contain only one applicator 10 and one container 20. Optionally, for backup, three or more containers 20 can be contained. Generally, the applicator 10 and the container 20 are placed separately at different positions in the package 200, for example, fixed by different foam pads. Of course, it is also possible that the container 20 is directly installed in the applicator 10, and then the whole is installed in the package 200.

[0053] Optionally, the container 20 is an ampoule, which is a device that is easily crushed. The applicator 10 can be used to crush it, thereby releasing the liquid in the container 20. Of course, the container 20 can also be a plastic bottle. Optionally, refer to Figure 1 The outside of the container 20 is provided with an easy-tear portion 21, wherein the easy-tear portion 21 is arranged along the length direction of the container 20. The design of the easy-tear portion 21 also facilitates the release of the liquid in the container 20.

[0054] Please refer to Figure 2-Figure 21 , the coating device 100 will be described in detail below.

[0055] Please refer to Figure 2-Figure 4 The coating device 100 comprises a container 20 and an applicator 10. Unless otherwise specified, the container 20 below mainly takes an ampoule bottle as an example.

[0056] The applicator 10 includes a housing 11 and a pressing structure 12 configured to directly act on the container 20 . The housing 11 is formed with a container accommodating cavity 110 . The container accommodating cavity 110 is configured to assemble the container 20 . The pressing structure 12 is disposed on the housing 11 .

[0057] The operator uses the pressing structure 12 to directly act on the container 20, that is, the pressure applied by the operator to the pressing structure 12 directly acts on the container 20, the force transmission is more direct, and the deformation or tearing of the container 20 is used to release the liquid, which can greatly reduce the pressing force applied by the operator and improve operability.

[0058] Optionally, a pressing hole 113 is formed through the shell 11 , and the pressing hole 113 is communicated with the container accommodating cavity 110 . The pressing structure 12 is configured to directly act on the container 20 in the container accommodating cavity 110 through the pressing hole 113 .

[0059] It should be noted that the pressing structure 12 provided in this embodiment can directly act on the surface of the container 20 through the pressing hole 113, thereby crushing the container 20. It can be understood that since the pressing structure 12 directly contacts the container 20, the external force applied by the operator directly acts on the container 20, which can effectively crush the container 20 and release the liquid.

[0060] Of course, when the container 20 is made of plastic, the tearable portion 21 on the container 20 can be configured to directly interact with the pressing structure 12 so that the pressing structure 12 can more easily break the container 20 through the tearable portion 21 to release the liquid.

[0061] by Figure 2 The relative position in Figure 2 The up, down, left, right, front, and back directions shown in Figure 2 , or the relative position relationship of the product when it is normally placed. Optionally, the front end of the shell 11 is the distal end, and the rear end of the shell 11 is the proximal end. The distal end of the shell 11 is connected to the smear cotton 182, and the liquid released after the container 20 is crushed can flow to the smear cotton 182 at the front end of the shell 11. The proximal end of the shell 11, that is, the rear end of the shell 11 is connected to the end cap 16, and the end cap 16 serves to install and fix the container 20. During assembly, the container 20 enters the container accommodating cavity 110 through the rear end of the shell 11, and then the end cap 16 is installed at the rear end of the shell 11, thereby sealing the container accommodating cavity 110 to fix the container 20.

[0062] Optionally, the end cap 16 and the housing 11 are detachably connected. This facilitates the separate production of the end cap 16, making the production more convenient. Optionally, the end cap 16 and the housing 11 are integrally formed, and the end cap 16 can be connected to the housing 11 in a flipped form. During assembly, the end cap 16 is flipped to open the rear end of the housing 11, so that the container 20 can enter the container receiving chamber 110 through the rear end of the housing 11, and then the end cap 16 is flipped in the opposite direction to reset the end cap 16, thereby sealing the container receiving chamber 110.

[0063] In this embodiment, the shell 11 is a hollow rod-shaped structure, and the internal cavity of the shell 11 is configured to form a container accommodating chamber 110, wherein the container accommodating chamber 110 is arranged along the length direction of the shell 11, that is, the container accommodating chamber 110 extends along the front-to-back direction of the shell 11.

[0064] Optionally, the container accommodating cavity 110 is configured to accommodate at least two containers 20 , the pressing structure 12 is connected to the outer wall 112 of the shell 11 , and the pressing structure 12 is configured to directly act on at least one container 20 in the container accommodating cavity 110 .

[0065] Optionally, the pressing structure 12 and the outer wall 112 of the shell 11 are detachably connected, so that the pressing structure 12 can be produced separately and manufactured more conveniently. After manufacturing, the pressing structure 12 can be assembled to the shell 11 in the production workshop, or the operator can purchase it and install it by himself.

[0066] Optionally, the pressing structure 12 and the outer wall 112 of the housing 11 may be integrally formed, thereby reducing the number of installation steps and improving assembly efficiency.

[0067] Optionally, the pressing hole 113 penetrates the outer shell 11 along the direction from the outer wall 112 to the inner wall 111 of the outer shell 11 and communicates with the container accommodating chamber 110. The direction from the outer wall 112 to the inner wall 111 can also be understood as the radial direction of the outer shell 11, that is, Figure 2-Figure 4 The direction from the outer wall 112 to the inner wall 111 can be understood as the up-down direction. In this way, the pressing structure 12 can directly act on the container 20 in the container accommodating cavity 110 through the pressing hole 113 along the up-down direction to achieve the crushing of the container 20.

[0068] Of course, the pressing structure 12 can also be threadedly matched with the pressing hole 113. For example, the pressing structure 12 is provided with an external thread, and the pressing hole 113 is provided with an internal thread, and the external thread of the pressing structure 12 and the internal thread of the pressing hole 113 are threadedly matched, so that after the pressing structure 12 is inserted into the pressing hole 113, the pressing structure 12 is rotated so that the pressing structure 12 is threadedly screwed into the container accommodating cavity 110 and directly acts on the container 20 to achieve crushing. By setting the pressing structure 12 and the pressing hole 113 to be threadedly matched, the stability of crushing by manual operation can be guaranteed.

[0069] The housing 11 can be manufactured by extrusion molding (or extrusion molding), and the pressing hole 113 can be formed by lateral cutting (e.g., left-right direction) or vertical opening (e.g., up-down direction). In order to avoid reducing the strength of the housing 11 due to the opening, optionally, a first reinforcing rib 117 can be formed on the outer wall 112 of the housing 11. The first reinforcing rib 117 can improve the bending resistance and torsional deformation resistance of the housing 11, so that the housing 11 is not prone to permanent deformation or fracture when subjected to external force.

[0070] Among them, a first reinforcing rib 117 is provided on the upper side of the shell 11, and the first reinforcing rib 117 is provided along the front-back direction of the shell 11. Of course, two or more first reinforcing ribs 117 can be provided on the shell 11, and no specific limitation is made here. Similarly, the first reinforcing rib 117 can also be provided on the lower side of the shell 11. The shape of the first reinforcing rib 117 can also be annular, and it extends around the circumference of the shell 11.

[0071] It should be noted that after the container 20 is broken, the operator generally tilts the shell 11 at a certain angle, and the liquid can flow smoothly downward to the smear cotton 182. Of course, after the pressing hole 113 is formed on the shell 11, the liquid may leak out through the pressing hole 113.

[0072] In order to solve this technical problem, optionally, the pressing structure 12 is configured to be sealed with the pressing hole 113. The pressing structure 12 breaks the container 20, and the liquid in the container 20 flows out. The sealing cooperation between the pressing structure 12 and the pressing hole 113 can prevent the liquid from flowing out of the shell 11, thereby avoiding contamination.

[0073] It is understandable that there are many ways of sealing. For example, an elastic ring is formed in the pressing hole 113. Optionally, the pressing structure 12 is provided with an elastic ring, etc., to achieve sealing through elastic deformation.

[0074] Of course, the pressing structure 12 can also be configured to be interference fit with the pressing hole 113 so as to block the pressing hole 113 and prevent the liquid in the container accommodating cavity 110 from flowing out of the pressing hole 113 .

[0075] Optionally, the outer shell 11 extends away from the container accommodating cavity 110 to form an enclosing shell 15 , the pressing hole 113 is located inside the enclosing shell 15 , one end of the pressing structure 12 is detachably connected to the enclosing shell 15 , and the pressing structure 12 can move inside the enclosing shell 15 .

[0076] In other words, the connection between the pressing structure 12 and the enclosing shell 15 is a detachable connection, which facilitates the separate production of the pressing structure 12 and makes the production more convenient. After the production is completed, the pressing structure 12 can be assembled to the outer shell 11 in the production workshop, or the operator can purchase it and install it by himself.

[0077] Optionally, a snap-in hole 151 is formed at one end of the enclosing shell 15, and a snap-in protrusion 1211 is formed at one end of the pressing structure 12, and the snap-in protrusion 1211 is snap-in with the snap-in hole 151. The snap-in protrusion 1211 of the pressing structure 12 cooperates with the snap-in hole 151. In the present embodiment, the left and right sides of the front end of the pressing structure 12 are provided with snap-in protrusions 1211, and the positions corresponding to the snap-in protrusions 1211 in the enclosing shell 15 are provided with snap-in holes 151. After the pressing structure 12 is arranged in the enclosing shell 15, the snap-in protrusion 1211 is snap-in in the snap-in hole 151, so as to realize the fixing of the pressing structure 12 in the enclosing shell 15. The pressing structure 12 is connected to the housing 11 by the snap-in protrusion 1211 being snap-in to the snap-in hole 151, so that it is not easy to fall off the housing 11, and it is ensured that the front end of the pressing structure 12 will not fall off during the pressing process.

[0078] It can be understood that the front end of the pressing structure 12 is detachably connected to the housing 11, and the operator presses the rear end of the pressing structure 12 to enable the pressing structure 12 to act on the container 20 in the container receiving cavity 110. Of course, the clamping protrusion 1211 of the pressing structure 12 can also be set at the rear end of the pressing member 121. This method can be understood as that the operator presses the front end of the pressing structure 12 to enable the pressing structure 12 to act on the container 20 in the container receiving cavity 110.

[0079] Optionally, a hollow shell structure may be formed at the front end of the pressing structure 12, for example, a thinner design may be adopted to facilitate deformation of the front end of the pressing structure 12, and at the same time, materials and costs may be saved to a certain extent.

[0080] Optionally, refer to Figure 3 Combined with Figure 2 The pressing structure 12 includes a pressing member 121 and a crushing member 122. The pressing member 121 is connected to the housing 11, and the crushing member 122 is connected to the pressing member 121. Under the action of external force, the pressing member 121 drives the crushing member 122 to be inserted into the pressing hole 113 and directly acts on the surface of the container 20, thereby crushing the container 20. The distal end of the pressing member 121, that is, the front end of the pressing member 121 forms a connecting end 1212. The connecting end 1212 can be integrally formed with the housing 11, or can be detachably connected to the housing 11. Optionally, a snap-fitting protrusion 1211 is formed on the connecting end 1212, and the connecting end 1212 is detachably connected to the housing 11 through the snap-fitting protrusion 1211.

[0081] Optionally, combined Figure 3 A sealing convex ring 1220 is formed on the pressing structure 12, and the sealing convex ring 1220 is configured to seal with the pressing hole 113. When the pressing structure 12 passes through the pressing hole 113, the sealing convex ring 1220 can seal the gap between the pressing structure 12 and the pressing hole 113, thereby preventing liquid leakage.

[0082] Optionally, the pressing structure 12 includes a pressing member 121 and a crushing member 122, the pressing member 121 is connected to the housing 11, and a sealing protrusion 1220 is convexly disposed on the outer surface of the crushing member 122. The two ends of the pressing member 121 are respectively a connecting end 1212 and a pressing end 1213, that is, the distal end of the pressing member 121 is the connecting end 1212, the proximal end of the pressing member 121 is the pressing end 1213, the clamping protrusion 1211 is disposed on the connecting end 1212, the crushing member 122 is connected to the middle part of the pressing member 121, and the pressing end 1213 is pressed downwardly with force, thereby driving the crushing member 122 to pass through the pressing hole 113 and directly act on the surface of the container 20 for crushing.

[0083] Optionally, along the direction from the inner wall 111 to the outer wall 112 of the housing 11, which direction from the outer wall 112 to the inner wall 111 can be understood as the up-down direction, the size of the pressing hole 113 gradually decreases, so that the pressing hole 113 can wrap around the crushing part 122, exerting a tightening external force on the crushing part 122, thereby further achieving the sealing of the pressing hole 113 and the crushing part 122. Of course, the size of the pressing hole 113 can also remain unchanged. In other words, the cross-sectional shape of the pressing hole 113 can be a conical surface or a straight surface.

[0084] It should also be noted that the thickness of the portion of the housing 11 configured to form the pressing hole 113 is greater than the thickness of the other portions of the housing 11. This facilitates the formation of the pressing hole 113. Generally speaking, a thickening layer is first designed at the position of the pressing hole 113 on the housing 11, and then a hole is opened laterally to avoid affecting the structural stability of the housing 11 itself. The thickening layer here can be embodied in the structural form of the first reinforcing rib 117.

[0085] Optionally, the applicator 10 further includes a dyed filter cotton 181, which is disposed at the front end of the housing 11. Generally, the liquid in the container 20 is colorless, and there may be fragments after the container 20 is crushed. The dyed filter cotton 181 can filter such fragments and impurities, and at the same time, in the process of the liquid flowing to the applicator cotton 182, the liquid can be dyed because it contacts the dyed filter cotton 181. The flow of the liquid can be intuitively displayed through the color change, which is also convenient for observing the application after applying it to the human body. In addition, if there is a liquid leakage, it can be discovered at the first time.

[0086] Optionally, a partition bar 114 is protruding from the inner wall 111 of the shell 11. The partition bar 114 is arranged on the inner wall 111 of the shell 11 along the front-to-back direction. The partition bar 114 can separate at least two containers 20 located in the shell 11. Optionally, two containers 20 are stored in the container accommodating cavity 110. In this way, the partition bar 114 can separate the two containers 20 and fix the two containers 20.

[0087] Optionally, the dividing bar 114 may be protruded from the bottom inner wall 111 of the housing 11 along the front-to-back direction, and the length of the dividing bar 114 may be very small, as long as the dividing bar 114 can separate at least two containers 20 in the container receiving chamber 110. Of course, the length of the dividing bar 114 may also be very long, and may even be consistent with the length of the container receiving chamber 110, thereby separating the interior of the container receiving chamber 110 into two chambers to respectively receive the containers 20, further ensuring that the containers 20 can be stably received in the container receiving chamber 110, so as to facilitate better crushing later.

[0088] Please refer to Figure 2-Figure 6 Optionally, the housing 11 is provided with at least one first limiting portion 152, and the pressing structure 12 is provided with at least one second limiting portion 125, and the first limiting portion 152 is configured to cooperate with the second limiting portion 125. Through the limiting cooperation, the false triggering or locking of the pressing structure 12 can be achieved, which will be described in detail below with reference to the accompanying drawings.

[0089] For example, when the pressing structure 12 is pressed, the first limiting portion 152 and the second limiting portion 125 come into contact, blocking the downward stroke of the pressing structure 12. At this time, a relatively large force is required to continue pressing the pressing structure 12. Only after overcoming the blocking force of the first limiting portion 152 and the second limiting portion 125 can the container 20 be crushed. At this time, the first limiting portion 152 and the second limiting portion 125 play a role in preventing false triggering, thereby preventing the applicator 10 from being accidentally triggered during transportation.

[0090] For example, after the pressing structure 12 breaks the container 20, if it is necessary to maintain the breaking state of the container 20 by the pressing structure 12, the pressing structure 12 can maintain the breaking state through the limiting and locking functions of the first limiting portion 152 and the second limiting portion 125. Optionally, after the pressing structure 12 breaks the container 20 through the pressing hole 113 on the housing 11, the pressing state is maintained, so that the pressing structure 12 always seals the pressing hole 113 to prevent liquid leakage.

[0091] Optionally, an enclosure shell 15 is formed on the outer shell 11 to limit the pressing stroke of the pressing structure 12 .

[0092] Optionally, there are two first limiting portions 152, which are respectively formed on the top edge 1521 of the enclosure shell 15 and on the enclosure shell 15, and there are two second limiting portions 125, which are spaced apart along the vertical direction of the pressing structure 12, wherein the two first limiting portions 152 and the two second limiting portions 125 are matched one by one. The limiting match between the housing 11 and the pressing structure 12 is achieved by the two first limiting portions 152 and the two second limiting portions 125.

[0093] Optionally, the top edge 1521 of the enclosure shell 15 forms a first limiting portion 152 .

[0094] Optionally, the first limiting portion 152 and the second limiting portion 125 include a limiting hole 1522 and a limiting protrusion 1251 that cooperate with each other. Optionally, the first limiting portion 152 can be a hole, and the second limiting portion 125 can be a protrusion, or the first limiting portion 152 can be a protrusion, and the second limiting portion 125 can be a hole. Of course, it is not excluded that the first limiting portion 152 includes both a hole and a protrusion, and similarly, the second limiting portion 125 can also include both a protrusion and a hole.

[0095] by Figure 2 For example, generally, before pressing the pressing structure 12, the limiting protrusion 1251 can be above a fixed edge of the enclosure shell 15, or the limiting protrusion 1251 abuts against the top edge 1521 of the enclosure shell 15. Due to the existence of a certain blocking effect, false triggering can be prevented.

[0096] Moreover, after the pressing structure 12 is inserted into the pressing hole 113 and breaks the container 20, the limiting protrusion 1251 moves downward and is engaged in the limiting hole 1522 on the enclosing shell 15, thereby keeping the pressing structure 12 in a crushed state, so that the pressing structure 12 always remains in the pressing hole 113, which can seal the pressing hole 113 to a certain extent, while ensuring the crushing effect and avoiding the leakage of glass fragments caused by repeated pressing.

[0097] Optionally, the second limiting portion 125 includes two limiting protrusions 1251 protruding from the pressing structure 12 , which are a large limiting protrusion 1252 and a small limiting protrusion 1253 .

[0098] The first limiting portion 152 includes a limiting hole 1522 formed on the enclosure shell 15 , wherein the small limiting protrusion 1253 is configured to cooperate with the top edge 1521 of the enclosure shell 15 , and the large limiting protrusion 1252 is configured to cooperate with the limiting hole 1522 on the enclosure shell 15 .

[0099] When the pressing structure 12 is installed in the enclosing shell 15, the small limiting protrusion 1253 can cooperate with the limiting protrusion 1251 of the enclosing shell 15 to avoid false triggering. When the pressing structure 12 is pressed downward with force, the pressing structure 12 can pass through the pressing hole 113 to directly crush the container 20, and the large limiting protrusion 1252 can move downward and be inserted into the limiting hole 1522 of the enclosing shell 15, thereby maintaining the crushing state of the pressing structure 12, locking the pressing structure 12, and ensuring the crushing effect.

[0100] Optionally, the first limiting portion 152 may be formed only on the top edge 1521 of the enclosing shell 15, and the second limiting portion 125 includes two limiting protrusions 1251 protruding from the pressing structure 12, which are a large limiting protrusion 1252 and a small limiting protrusion 1253 respectively. When the pressing structure 12 is installed in the enclosing shell 15, the small limiting protrusion 1253 and the top edge 1521 of the enclosing shell 15 abut and cooperate with each other, thereby avoiding false triggering. When the pressing structure 12 is pressed downward with force, the pressing structure 12 can pass through the pressing hole 113 to directly break the container 20, and the large limiting protrusion 1252 can move downward and abut and cooperate with the top edge 1521 of the enclosing shell 15, thereby feeding back to the operator the information that the container 20 is broken.

[0101] Optionally, the first limiting portion 152 and the second limiting portion 125 only include a limiting hole 1522 and a limiting protrusion 1251 that cooperate with each other. The first limiting portion 152 includes a limiting hole 1522, and the second limiting portion 125 includes two limiting protrusions 1251 protruding from the pressing structure 12, which are a large limiting protrusion 1252 and a small limiting protrusion 1253. When the pressing structure 12 is installed in the enclosure shell 15, the small limiting protrusion 1253 and the limiting hole 1522 are engaged and matched, thereby avoiding the phenomenon of false triggering. When the pressing structure 12 is pressed downward with force, the pressing structure 12 can pass through the pressing hole 113 to directly crush the container 20, and the large limiting protrusion 1252 can move downward to be engaged in the limiting hole 1522 of the enclosure shell 15, thereby maintaining the crushing state of the pressing structure 12.

[0102] Optionally, the first limiting portion 152 includes two limiting holes 1522 spaced apart in the up-and-down directions, and the second limiting portion 125 includes only one limiting protrusion 1251. When the pressing structure 12 is installed in the enclosing shell 15, the limiting protrusion 1251 and the limiting hole 1522 located above are snap-fitted together to avoid false triggering. When the pressing structure 12 is pressed downward with force, the pressing structure 12 can pass through the pressing hole 113 to directly break the container 20, and the limiting protrusion 1251 moves downward to be snapped into the limiting hole 1522 located below, thereby maintaining the pressing state of the pressing structure 12.

[0103] Based on the above, it can be known that the number of the first limiting portion 152 and the second limiting portion 125 is not limited, and the specific form is not limited, as long as it can prevent accidental touch, or lock the pressing structure 12 to maintain its crushed state.

[0104] Optionally, refer to Figure 4-Figure 6 The crushing member 122 includes a crushing section 1221, a sealing section 1222 and a connecting section 1223 which are arranged in sequence. The connecting section 1223 is connected to the pressing member 121. The sealing section 1222 is configured to seal the pressing hole 113 when the crushing section 1221 acts on the container 20 in the container accommodating cavity 110 through the pressing hole 113. In this way, the connecting section 1223 follows the downward pressure of the pressing piece 121 to drive the sealing section 1222 and the crushing section 1221 to move downward, thereby entering the pressing hole 113, and the crushing section 1221 directly passes through the pressing hole 113 to enter the interior of the container accommodating cavity 110, thereby directly acting on the surface of the container 20, and the sealing section 1222 is arranged inside the pressing hole 113, and the sealing section 1222 can block the pressing hole 113 to form a seal, thereby preventing the liquid flowing out after the crushing section 1221 crushes the container 20 from leaking from the pressing hole 113.

[0105] Optionally, the connecting section 1223, the sealing section 1222 and the crushing section 1221 are connected in sequence and formed as one piece. After the operator presses the pressing piece 121, the crushing section 1221 passes through the pressing hole 113 under the drive of the pressing force, and the sealing section 1222 is in the pressing hole 113 and can seal the pressing hole 113 to prevent liquid leakage. The crushing section 1221 directly acts on the container 20 to crush the container 20. The sealing section 1222 is arranged inside the pressing hole 113, and the sealing section 1222 can seal the pressing hole 113, thereby preventing the liquid flowing out after the crushing section 1221 crushes the container 20 from leaking from the pressing hole 113.

[0106] Optionally, the thickness of the crushing section 1221 gradually increases along the direction from the crushing section 1221 to the connecting section 1223, that is, the thickness of the crushing section 1221 gradually increases from bottom to top, so that the sealing section 1222 can be closely abutted against the pressing hole 113, thereby sealing the pressing hole 113. During the pressing process, the lower end of the crushing section 1221 can enter the container accommodating cavity 110 and directly act on the surface of the container 20, thereby crushing the container 20 and causing the liquid inside to flow out. The middle end and the upper end of the crushing section 1221 can be located in the pressing hole 113 and squeeze the inside of the pressing hole 113, thereby blocking the pressing hole 113 and preventing the liquid from leaking out of the pressing hole 113. The crushing section 1221 is a flat structure as a whole, and its thickness can be understood as its distance along the front-back direction.

[0107] Of course, the crushing section 1221 may also have a taper, so as to easily pass through the pressing hole 113 and directly act on the container 20. The taper of the crushing section 1221 increases from top to bottom, so that the lower end of the crushing section 1221 can easily pass through the pressing hole 113 and directly act on the surface of the container 20, and the middle and upper ends of the crushing section 1221 can follow the sealing section 1222 to squeeze the pressing hole 113 to achieve a tight fit, thereby forming a seal to prevent liquid leakage.

[0108] In the above, the sealing convex ring 1220 can be formed on the sealing sub-portion 1222, can be formed on the crushing sub-portion 1221, or can be formed on the connecting sub-portion 1223. For example, the sealing convex ring 1220 is formed on the sealing sub-portion 1222. For example, the sealing convex ring 1220 is formed on the crushing sub-portion 1221. For example, the sealing convex ring 1220 is respectively arranged on the sealing sub-portion 1222 and the crushing sub-portion 1221, so that during the pressing process, the sealing sub-portion 1222 and the crushing sub-portion 1221 can both block the pressing hole 113 through the sealing convex ring 1220, thereby achieving sealing.

[0109] Optionally, combined Figure 5The pressing structure 12 is provided with anti-slip grooves 129 , which can increase the friction of the pressing structure 12 , ensure the stability of the operator when pressing, and help the operator to better press the pressing structure 12 to crush the container 20 .

[0110] Optionally, the anti-slip pattern 129 is disposed on the top surface of the pressing piece 121 and mainly covers the pressing end 1213 of the pressing piece 121 . The anti-slip pattern 129 can increase the friction force on the surface of the pressing end 1213 , thereby helping the operator to better press the pressing end 1213 .

[0111] Of course, the anti-slip grooves 129 can also completely cover the top surface of the pressing piece 121, that is, the entire top surface of the pressing piece 121 can be provided with anti-slip grooves 129, thereby increasing the friction of the top surface of the pressing piece 121 and helping the operator to better press down the pressing piece 121.

[0112] Optionally, the anti-slip pattern 129 includes a plurality of convex strips, which are arranged at intervals in the front-to-back direction at the action end of the pressing piece 121. During the pressing process, when the operator presses the pressing end 1213 of the pressing piece 121, the anti-slip pattern 129 can increase the friction force, thereby helping the operator to better press the pressing end 1213.

[0113] Please refer to Figure 7 In order to seal the pressing hole 113, optionally, part of the outer wall 112 of the housing 11 extends away from the container accommodating chamber 110 to form an annular sealing portion 13, and one end of the annular sealing portion 13 away from the outer wall 112 forms a port 131 communicating with the pressing hole 113. When the pressing structure 12 is pressed, it enters the pressing hole 113 through the port 131 of the annular sealing portion 13, and the annular sealing portion 13 can seal the gap between the pressing structure 12 and the pressing hole 113 to prevent liquid leakage.

[0114] Optionally, during the process of inserting the crushing section 1221 of the crushing member 122 into the pressing hole 113, the sealing section 1222 of the crushing member 122 squeezes the port 131 of the annular sealing portion 13 and drives the port 131 of the annular sealing portion 13 to move toward the pressing hole 113, thereby realizing an inner buckle seal. In other words, during the process of pressing the crushing member 122 downward, the crushing section 1221, the sealing section 1222 and the connecting section 1223 will sequentially exert a downward force on the annular sealing portion 13, causing the port 131 of the annular sealing portion 13 to move downward to form an inner buckle, thereby sealing the gap between the pressing structure 12 and the pressing hole 113 to prevent liquid leakage.

[0115] Optionally, the port 131 of the annular sealing portion 13 is configured to be gap-matched with the pressing structure 12, for example, the port 131 is gap-matched with the crushing sub-portion 1221 of the pressing structure 12. In this way, the crushing sub-portion 1221 can directly enter the pressing hole 113 from the port 131 and finally enter the container accommodating cavity 110, ensuring that the crushing sub-portion 1221 can better crush the container 20.

[0116] Optionally, the port 131 of the annular sealing portion 13 is further configured to be interference fit with the pressing structure 12, for example, the port 131 is interference fit with the sealing sub-portion 1222 of the pressing structure 12. In this way, when the crushing sub-portion 1221 enters the container accommodating cavity 110 to crush the container 20, the sealing sub-portion 1222 can squeeze the port 131 of the annular sealing portion 13 and the pressing hole 113, thereby forming a seal to prevent liquid leakage.

[0117] Optionally, along the direction from the inner wall 111 to the outer wall 112 of the outer shell 11, the outer circumferential dimension of the annular sealing portion 13 gradually decreases, and the periphery of the annular sealing portion 13 has an inclination, that is, the size of the annular sealing portion 13 is larger on the outside and smaller on the inside. Due to the inclination of the annular sealing portion 13, after the crushing piece 122 is inserted into the pressing hole 113, the annular sealing portion 13 can be further allowed to deform, that is, the sealing portion 1222 of the crushing piece 122 further drives the annular sealing portion 13 to be concave inward for extrusion and buckling, thereby realizing an inner buckle seal.

[0118] Optionally, a deformation groove 132 is formed at least partially around the annular sealing portion 13. For example, a deformation groove 132 is formed at the front end of the annular sealing portion 13. For example, a deformation groove 132 is formed at the rear end of the annular sealing portion 13. For example, a deformation groove 132 is formed on the left side of the annular sealing portion 13. For example, a deformation groove 132 is formed on the right side of the annular sealing portion 13. In the above, the deformation groove 132 can be set in one or more ways, which is not specifically limited here. The deformation of the annular sealing portion 13 in the front-to-back direction and the left-to-right direction is achieved by setting the deformation groove 132, thereby facilitating the cooperation between the annular sealing portion 13 and the crushing member 122.

[0119] Optionally, deformation grooves 132 are formed on the outer periphery of the annular sealing portion 13. Since the movement trajectory of the crushing piece 122 is arc-shaped during the downward movement of the crushing piece 122 under pressure, the deformation grooves 132 on the outer periphery of the annular sealing portion 13 can be used to deform the annular sealing portion 13 in the front-to-back direction, thereby facilitating the coordination between the annular sealing portion 13 and the crushing piece 122. In addition, the force generated by the annular sealing portion 13 when deformed can facilitate the extrusion of the annular sealing portion 13, further facilitating the sealing of the pressing hole.

[0120] Optionally, the annular sealing portion 13 can be integrally formed with the housing 11. Alternatively, the annular sealing portion 13 can be made of a soft material alone and then sealed with the housing. Alternatively, the annular sealing portion 13 and the housing 11 are integrally formed, but the housing 11 is made of a hard material, while the annular sealing portion 13 is made of a soft material. The deformable characteristics of the annular sealing portion 13 can be used to achieve a better seal with the sealing sub-portion 1222. Optionally, the annular sealing portion 13 can also be made of other deformable materials, which are not specifically limited here.

[0121] Optionally, refer to Figure 7 The housing 11 is provided with an air vent 118, which is in communication with the container receiving chamber 110. The air vent 118 is provided at the proximal end of the housing 11, i.e., the rear end of the housing 11, and the air vent can be used to introduce air into the container receiving chamber 110 in the housing 11, thereby balancing the pressure inside the container receiving chamber 110 and preventing the housing 11 from being deformed due to the pressure difference. In addition, due to the existence of the air vent 118, when the container in the container receiving chamber 110 is crushed and the liquid flows out, the container receiving chamber can be connected to the atmosphere through the air vent, which is conducive to the normal flow of the liquid.

[0122] Optionally, the proximal end of the shell 11, i.e., the rear end of the shell 11, is formed with an annular protrusion 115, and the annular protrusion 115 cooperates with the end cover 16, so that the end cover 16 closes the proximal end of the shell 11, i.e., the rear end of the shell 11. The end cover 16 plays a role in installing and fixing the container 20. During assembly, the container 20 enters the container accommodating cavity 110 through the rear end of the shell 11, and then the end cover 16 cooperates with the annular protrusion 115 at the rear end of the shell 11, thereby sealing the container accommodating cavity 110 to fix the container 20.

[0123] Optionally, the air vent 118 is longer in the front-to-rear direction of the shell, so that when the end cover is installed to the rear end of the shell, a portion of the air vent can be directly exposed to the shell to achieve direct communication with the atmosphere.

[0124] Please refer to Figure 8 The end cover 16 includes a bottom wall 161, a peripheral wall 162, and a boss 163. The peripheral wall 162 is connected to the bottom wall 161, and the boss 163 is disposed on the bottom wall 161. An annular groove 165 is formed between the boss 163 and the peripheral wall 162, and the annular groove 165 is configured to be engaged with the proximal end of the housing 11, that is, the rear end of the housing 11. The peripheral wall 162 is formed with an annular groove 166, and the annular protrusion 115 is configured to be engaged in the annular groove 166.

[0125] During assembly, open the end cover 16, place the container 20 in the container accommodating cavity 110, and then match the annular groove 165 of the end cover 16 with the annular protrusion 115 of the shell 11, so that the end cover 16 closes the proximal end of the shell 11, that is, the rear end of the shell 11.

[0126] Optionally, a notch 1631 is formed on the boss 163, and the notch 1631 is connected to the vent hole 118. The notch is connected to the portion of the vent hole covered by the end cap, and the notch can facilitate the portion of the vent hole covered by the end cap to be connected to the atmosphere, thereby facilitating the introduction of air into the container accommodating cavity 110, thereby balancing the pressure inside the container accommodating cavity 110, and facilitating the normal flow of liquid.

[0127] Optionally, notches 1631 are provided at both ends of the boss 163, and the left and right sides of the shell are also connected to the air holes 118, so that the two notches 1631 are respectively connected to the two corresponding air holes 118, so that the part of the air hole covered by the end cover can also be connected to the atmosphere through the notch, which is conducive to the introduction of air into the container accommodating cavity 110 and the normal flow of liquid.

[0128] Optionally, since the liquid in the container 20 is generally colorless, the liquid in the container 20 may leak from the air hole 118. In order to prevent the liquid from leaking from the air hole 118, a color-changing sponge can be set at the position of the air hole 118. Once the color of the color-changing sponge changes, it means that the liquid in the container 20 has leaked, so that the operator can intuitively observe and find out whether there is any leakage of the liquid.

[0129] Optionally, a partition plate 164 is provided in the middle of the boss 163, and the partition plate 164 can separate the two containers 20 in the container accommodating chamber 110. The partition plate 164 can fix the rear ends of the two containers 20.

[0130] Optionally, third reinforcing ribs 167 are provided on both sides of the partition plate 164 , so that the connection between the partition plate 164 and the boss 163 is more stable, thereby ensuring the structural stability of the partition plate 164 .

[0131] Please refer to Fig. 9 The distal end of the housing 11 is formed with a mounting shell 17, the mounting shell 17 has an immersion space 172, and the smear cotton 182 is arranged at the distal end of the mounting shell 17. The immersion space 172 of the mounting shell 17 can ensure that whether the housing 11 is arranged vertically or tilted, the liquid flowing out after the container 20 is broken can be evenly filled with the smear cotton 182, thereby ensuring the subsequent smearing work.

[0132] Optionally, at least two layers of annular structures 171 are formed at the far end of the mounting shell 17, and the smear cotton 182 is connected to the annular structure 171. The annular structure 171 can ensure that the smear cotton 182 can be bonded to the inside of the mounting shell 17 after the hot melt process. After the hot melt connection, the number of the annular structure 171 may be two layers, or it may be hot-melted into one layer.

[0133] The setting of the annular structure 171 can better realize the connection between the mounting shell 17 and the smear cotton 182 to prevent liquid leakage. Of course, the smear cotton 182 can also be connected to the mounting shell 17 by heat welding or ultrasonic welding, which is not specifically limited here.

[0134] Optionally, a container distal end stopper 14 is formed in the shell 11. When the applicator 10 is in use, the applicator 10 as a whole will be in an inclined state, at this time the distal end of the shell 11 is downward, the proximal end of the shell 11, that is, the rear end of the shell 11 is upward, and the container 20 in the container accommodating cavity 110 will slide toward the distal end of the shell 11 under the action of its own gravity, and the container distal end stopper 14 can limit the container 20, preventing the container 20 from entering the smear cotton 182 connected to the distal end of the shell 11 as a whole, thereby fixing the position of the container 20.

[0135] Optionally, the container distal end stopper 14 is formed with a flow hole 141, and the flow hole 141 allows liquid to pass through. After the container 20 is crushed by the pressing structure 12, the liquid in the container 20 enters the smear cotton 182 connected to the distal end of the shell 11 through the flow hole 141, thereby ensuring the smooth progress of subsequent smearing work.

[0136] Optionally, the container distal end stopper 14 includes two convex pieces 142 disposed opposite to each other, and a flow hole 141 is formed between the two convex pieces 142 for liquid flow, and the flow hole 141 may be in the shape of an "8" figure, which is conducive to the liquid flowing out and fully infiltrating the dye filter cotton. Generally, the filter dye filter cotton can be disposed on the outside of the container distal end stopper 14, that is, the filter dye filter cotton is disposed at the front end of the container distal end stopper 14, and the container distal end stopper 14 limits the container 20.

[0137] Optionally, the dyeing filter cotton can also be arranged on the inner side of the container distal end stopper 14, that is, the filter dyeing filter cotton is arranged at the rear end of the container distal end stopper 14, so that the container 20 can directly abut against the filter dyeing filter cotton. Not only the container 20 is limited, but also the full flow of the liquid can be achieved.

[0138] Optionally, the distance between the container distal end stopper 14 and the pressing hole 113 is 0.5-2 cm. The installation of the container distal end stopper 14 within this distance range can prevent the container distal end stopper 14 from being too far forward, which makes the container 20 difficult to crush, and can also prevent the container distal end stopper 14 from being too far back, which makes the liquid flow path too long after the container 20 is crushed.

[0139] Optionally, the distance between the container distal end stopper 14 and the pressing hole 113 is 0.5 cm. Of course, the distance between the container distal end stopper 14 and the pressing hole 113 can also be 1 cm, 1.2 cm, 1.6 cm or 2 cm, etc., which is not specifically limited here.

[0140] When the applicator is in use, the liquid in the container 20 flows out and reaches the flow hole 141 through the dyed filter cotton 181, enters the immersion space 172 of the mounting shell 17 through the flow hole 141, and finally reaches the interior of the applicator cotton 182.

[0141] Please refer to Fig.10 Optionally, the number of the pressing structures 12 is at least two. At least two pressing structures 12 are connected to the housing 11. At least two pressing structures 12 are arranged on the housing 11. At least two pressing structures 12 can crush the same container 20 in the container accommodating cavity 110 through the pressing hole 113. In this way, even if one of the pressing structures 12 has the risk of failing to crush the container 20, the other pressing structure 12 can crush the container 20, thereby ensuring that the container 20 can be crushed to avoid affecting the subsequent application work.

[0142] Optionally, at least two pressing structures 12 can also crush different containers 20 in the container accommodating cavity 110 through the pressing holes 113. In this way, the plurality of pressing structures 12 can crush the plurality of containers 20 in the container accommodating cavity 110 accordingly.

[0143] This can be applied not only to ordinary application scenarios, but also to complex scenarios that require liquid mixing and proportioning. Of course, it can also be that in a certain scenario, a container is first crushed by a pressing structure for use, and after a period of use, another container is crushed by another pressing structure for use.

[0144] Optionally, there are two pressing structures 12, and they are distributed on both sides of the housing 11. The two pressing structures 12 are respectively distributed on the upper and lower sides of the housing 11. When in use, the two pressing structures 12 are pressed synchronously, thereby improving the application efficiency. Of course, the number of pressing structures 12 can also be adjusted according to actual conditions, and is not specifically limited here.

[0145] It should be noted that both sides of the housing 11 are penetrated with pressing holes 113, the pressing holes 113 are connected to the container accommodating cavity 110, and the pressing structure 12 is configured to directly act on the container 20 in the container accommodating cavity 110 through the corresponding pressing holes 113. It can be understood that the number of pressing structures 12 can correspond to the number of pressing holes 113 one by one, so that each pressing structure 12 can directly act on the container 20 through the corresponding pressing hole 113 to achieve crushing.

[0146] Optionally, the two pressing holes 113 on both sides of the shell 11 can be symmetrically arranged relative to the shell 11, so that the two pressing structures 12 on both sides of the shell 11 are respectively inserted into the two containers 20 in the container accommodating cavity 110 through the corresponding two pressing holes 113 to achieve synchronous crushing.

[0147] Optionally, the two pressing holes 113 on both sides of the shell 11 are staggered in the front-to-back direction of the shell 11, so that the pressing structure 12 on one side of the shell 11 is inserted into one side of the same container 20 in the container accommodating cavity 110 through the corresponding pressing hole 113, and the pressing structure 12 on the other side of the shell 11 is inserted into the other side of the same container 20 in the container accommodating cavity 110 through the corresponding pressing hole 113 to achieve crushing. In this way, even if one of the pressing structures 12 has the risk of failing to crush the container 20, the other pressing structure 12 can crush the container 20, thereby ensuring that the container 20 can be crushed to avoid affecting the subsequent application work.

[0148] Optionally, the two pressing holes 113 on both sides of the shell 11 are staggered in the front-to-back direction of the shell 11, so that the two pressing structures 12 on both sides of the shell 11 are respectively inserted into the opposite sides of the two containers 20 in the container accommodating cavity 110 through the corresponding two pressing holes 113 to achieve synchronous crushing or one-by-one crushing.

[0149] Optionally, the two pressing holes 113 on both sides of the shell 11 are staggered in the left and right directions of the shell 11, so that the two pressing structures 12 on both sides of the shell 11 are respectively inserted into the same position of different containers 20 in the container accommodating cavity 110 through the corresponding two pressing holes 113, thereby achieving synchronous crushing or one-by-one crushing.

[0150] Optionally, the two pressing holes 113 on both sides of the shell 11 are staggered in the left and right directions of the shell 11, so that the two pressing structures 12 on both sides of the shell 11 are respectively inserted into the front and rear positions of different containers 20 in the container accommodating cavity 110 through the corresponding two pressing holes 113 to achieve synchronous crushing or one by one crushing.

[0151] Please refer to Fig.11 Optionally, in order to prevent the liquid flowing out after the container 20 is crushed from leaking from the pressing hole 113, the applicator 10 in this embodiment further includes a sealing structure 183, which is disposed at the pressing hole 113. The sealing structure 183 can seal the pressing hole 113 to prevent the liquid flowing out after the container 20 is crushed from leaking from the pressing hole 113.

[0152] Optionally, the sealing structure 183 may be an elastic structure such as a rubber ring, a silicone ring or a film, and there may be a gap in the middle of the sealing structure 183, or an easy-to-tear dashed line may be set in the middle of the sealing structure 183, or an easy-to-tear dashed line may be set at a weak position of the sealing structure 183, so that the crushing member 122 needs to pass through the gap of the sealing structure 183 during the process of inserting the pressing hole 113 to enter the container accommodating cavity 110 to crush the container 20. Alternatively, the crushing member 122 needs to pass through the dashed line of the sealing structure 183 during the process of inserting the pressing hole 113 to enter the container accommodating cavity 110 to crush the container 20. The setting of the sealing structure 183 can prevent the leakage of liquid after the container 20 is crushed.

[0153] Optionally, the applicator 10 may further include a tear film 184, which covers the pressing hole 113. The breaking member 122 needs to break the tear film 184 during the insertion into the pressing hole 113 to enter the pressing hole 113 and finally reach the container accommodating cavity 110, thereby breaking the container 20.

[0154] Optionally, the pressing hole 113 may only be provided with a sealing structure 183 , and the pressing hole 113 is sealed by the sealing structure 183 , thereby preventing leakage of liquid after the container 20 is crushed.

[0155] Optionally, the pressing hole 113 may only be provided with an easy-tear film 184 , and the easy-tear film 184 covers the pressing hole 113 to achieve sealing, thereby preventing leakage of liquid after the container 20 is crushed.

[0156] Please refer to Fig.12 Optionally, the pressing structure 12 has at least two crushing sections 1221, and the at least two crushing sections 1221 have a height difference along the up-down direction, and the at least two crushing sections 1221 are respectively configured to directly act on at least two containers 20 in the container accommodating cavity 110 in sequence. By providing at least two crushing sections 1221 with a height difference, during the pressing process, the at least two crushing sections 1221 can crush at least two containers 20 in sequence, so that the liquids in the at least two containers 20 are released one by one in sequence, and the usage scenarios are more diverse.

[0157] Taking the pressing structure with two crushing sections 1221 as an example, since the two crushing sections 1221 have a height difference, if the operator's force is small, he can first use a certain force to press a certain distance to crush one container, and then use a certain force to continue pressing a certain distance to crush another container. This is convenient for operators with less grip strength to use.

[0158] Optionally, at least two crushing sections 1221 are formed on the crushing member 122, and the bottom surfaces of the two crushing sections 1221 have a height difference, so that when the two crushing sections 1221 press down the two containers 20 in the container accommodating chamber 110, the two crushing sections 1221 crush the two containers 20 in sequence, thereby ensuring that the liquids in the two containers 20 are released in a predetermined order, first releasing the liquid in one container 20, and then releasing the liquid in the other container 20. Alternatively, if the operator's force is small, a certain force can be used to press a certain distance to crush one container, and then a certain force can be used to continue pressing a certain distance to crush another container, which is convenient for operators with small grip strength to use.

[0159] Furthermore, when the two containers 20 in the container accommodating cavity 110 are crushed at the same time, a large number of bubbles are easily generated, thereby affecting the final coating effect. By setting two crushing sections 1221 with height differences, the liquids in the two containers 20 are released step by step, thereby reducing the probability of bubble generation, thereby ensuring the subsequent coating effect.

[0160] Optionally, the number of the crushing sections 1221 can be two, three or even more, and the number of the crushing sections 1221 can correspond one-to-one to the number of containers 20 in the container accommodating cavity 110. The bottom surface of each crushing section 1221 has a height difference, thereby achieving one-by-one crushing of multiple containers 20.

[0161] Please refer to Fig.13 The second limiting portion 125 includes a limiting protrusion 1251, and the first limiting portion 152 includes a limiting hole 1522. After the pressing structure 12 is pressed down, it is inserted into the pressing hole 113 and directly acts on the container 20 to crush it. After crushing, the limiting protrusion 1251 is engaged with the limiting hole 1522 during the pressing process of the pressing structure 12, thereby maintaining the crushed state of the pressing structure 12.

[0162] Optionally, the first limiting portion 152 may be a rack provided on the housing 11, and the second limiting portion 125 may be a block provided on the pressing structure 12. It can be understood that the rack includes a plurality of teeth, and the block cooperates with teeth at different positions on the rack, thereby keeping the pressing structure 12 at different positions, and preventing the pressing structure 12 from being repeatedly pressed and crushed.

[0163] Please refer to Figure 14-15 The position where the pressing structure 12 is connected to the shell 11 is A, the position where the pressing structure 12 is directly applied to the container 20 in the container accommodating cavity 110 is B, and the position where the pressing structure 12 is pressed is C, wherein the distance from A to B is smaller than the distance from B to C.

[0164] Through the above arrangement, the distance between the connection position of the pressing structure 12 and the shell 11 and the position where the pressing structure directly acts on the container 20 in the container accommodating cavity 110 is smaller than the distance between the position where the pressing structure directly acts on the container 20 in the container accommodating cavity 110 and the position pressed on the pressing structure, so that the pressing structure 12 can form a force-saving lever structure, ensuring that the pressing structure 12 can apply a smaller force to break the container 20 in the container accommodating cavity 110, which is more labor-saving when used.

[0165] Optionally, the pressing piece 121 is a rod-shaped structure, and the two ends of the pressing piece 121 are respectively a connecting end 1212 and a pressing end 1213, the connecting end 1212 of the pressing piece 121 is connected to the outer shell 11, the crushing piece 122 is connected to the side of the pressing piece 121 close to the outer shell 11, the connection position between the connecting end 1212 of the pressing piece 121 and the outer shell 11 is A, the position where the crushing section 1221 of the crushing piece 122 directly acts on the container 20 is B, and the position of the pressing end 1213 of the pressing piece 121 is C.

[0166] like Fig.15 As shown, A, B, and C are connected by dotted lines, and it can be seen that the distance between the connection end 1212 and the crushing sub-section 1221 is smaller than the distance between the crushing sub-section 1221 and the pressing end 1213. In other words, the crushing sub-section 1221 is arranged at a position closer to the connection end 1212. When the crushing sub-section 1221 contacts the surface of the container 20, the connection end 1212, the crushing sub-section 1221, and the pressing end 1213 can form a labor-saving lever structure. Since the distance between the crushing sub-section 1221 and the connection end 1212 is smaller than the distance between the crushing sub-section 1221 and the pressing end 1213, that is, the resistance arm formed between the crushing sub-section 1221 and the connection end 1212 is smaller than the power arm formed between the crushing sub-section 1221 and the pressing end 1213. According to the lever principle, since the power arm is larger than the resistance arm, applying a relatively small force on the pressing end 1213 can cause the crushing section 1221 to puncture the container 20, thereby achieving a labor-saving effect.

[0167] Optionally, the pressing end 1213 of the pressing member 121 is configured to drive the crushing member 122 to directly act on the container 20 in the container accommodating cavity 110 when pressed. The force transmission is more direct, which can greatly reduce the pressing force applied by the operator and improve the operability.

[0168] Optionally, the crushing member 122 is configured to be in the shape of a pointed cone at one end directly acting on the container 20. Optionally, the end of the crushing section 1221 directly acting on the container 20 is in the shape of a pointed cone, so that the crushing section 1221 and the container 20 form a line contact when in contact, and the container 20 can be punctured with less force, which is more labor-saving and improves the certainty of breaking the container 20.

[0169] Optionally, the end of the crushing section 1221 directly acting on the container 20 may also be in a columnar structure, so that the crushing section 1221 and the container 20 form a point contact when in contact, thereby concentrating the downward force and puncturing the container 20 at one time.

[0170] Optionally, the first limiting portion 152 is in the shape of a barb and is convexly disposed on the housing 11, the second limiting portion 125 is formed at the pressing end 1213 of the pressing structure 12, and the first limiting portion 152 is configured to be engaged with the second limiting portion 125. Optionally, when the crushing member 122 of the applicator 10 breaks the ampoule bottle across the housing 11, it is impossible to determine whether the ampoule bottle has been broken, which is not convenient to use. In order to solve this technical problem, the first limiting portion 152 is arranged between the pressing member 121 and the housing 11, and the first limiting portion 152 is connected to the outside of the housing 11. The first limiting portion 152 is used to hook the top surface of the second limiting portion 125 after the crushing section 1221 punctures the container 20, thereby keeping the pressing member 121 in the punctured state. Among them, the position of the first limiting portion 152 corresponds to the position of the pressing end 1213, the first limiting portion 152 is protruded on the upper side of the shell 11, and the height of the first limiting portion 152 is less than the height of the crushing section 1221. The first limiting portion 152 is used to abut against the top surface of the second limiting portion 125 after the crushing section 1221 punctures the container 20, thereby maintaining the punctured state of the crushing section 1221.

[0171] In this embodiment, the height of the first limit portion 152 is less than the height of the crushing sub-portion 1221, which means that during the downward movement of the pressing end 1213, the crushing sub-portion 1221 will first contact the container 20. When the crushing sub-portion 1221 contacts the container 20, there is a gap between the first limit portion 152 and the pressing end 1213. After the crushing sub-portion 1221 punctures the container 20, the pressing end 1213 will continue to move downward. When the surface of the second limit portion 125 of the pressing end 1213 abuts against the barb of the first limit portion 152, the pressing member 121 remains in the punctured state. When the top of the first limit portion 152 abuts against the top surface of the second limit portion 125 of the pressing end 1213, the operator can confirm that the container 20 has been broken.

[0172] Optionally, a sealing convex ring 1220 is formed on the crushing member 122, and the sealing convex ring 1220 is convexly arranged on the outer surface of the crushing member 122, and the sealing convex ring 1220 is configured to be sealed with the pressing hole 113. When the crushing member 122 passes through the pressing hole 113, the sealing convex ring 1220 can seal the gap between the crushing member 122 and the pressing hole 113, thereby preventing liquid leakage.

[0173] Optionally, the housing 11 and the connecting end 1212 of the pressing member 121 are integrally formed, thereby reducing the number of installation steps and saving time.

[0174] Optionally, refer to Fig.15 A thinning area 120 is formed at the connection position of the pressing structure 12 and the housing 11. Thus, the thickness of the connection position of the pressing structure 12 and the housing 11 is reduced, so that the connection position is more likely to deform during the pressing process of the operator, making the pressing process smoother.

[0175] Please refer to Fig.16 , an unlocking member 126 is provided on the housing 11 or the pressing structure 12. The unlocking member 126 is connected to the proximal end of the first limiting portion 152 close to the housing 11, that is, one side of the rear end of the housing 11. When the pressing member 121 does not need to be locked, the unlocking member 126 can move downward under the action of an external force, thereby driving the first limiting portion 152 to rotate clockwise and deform, thereby releasing the first limiting portion 152 from limiting the second limiting portion 125 of the pressing member 121, and achieving unlocking.

[0176] In this embodiment, the unlocking member 126 is a square block structure. The unlocking member 126 moves backward, thereby driving the first limiting portion 152 to move backward, so that the barb of the first limiting portion 152 leaves the top surface of the second limiting portion 125, and no longer continuously applies a downward pressure to the second limiting portion 125, and the second limiting portion 125 rebounds upward to achieve reset unlocking. When waste recycling is required, if one end of the pressing structure is detachably connected to the shell, the pressing structure can be easily removed by unlocking. If one end of the pressing structure is integrally formed with the shell, the end connecting the pressing structure and the shell can be broken off by unlocking.

[0177] Please refer to Fig.17 The pressing structure 12 includes a pressing member 121 and at least one pulling rib 127. The pressing member 121 is connected to the housing 11. At least one pulling rib 127 is connected to the pressing member 121. The pulling rib 127 is arranged around the housing 11. The pressing member 121 is connected to the housing 11 through the pulling rib 127 to ensure connection stability. The pulling rib 127 is deformed by the downward pressure of the pressing member 121. The pulling rib 127 drives the container 20 in the container accommodating cavity 110 to deform, thereby breaking the container 20 and rupturing it.

[0178] It should be noted that the front end of the pressing member 121 is connected to the outer shell 11, and the front end of the outer shell 11 is provided with a pulling rib 127. When in use, the rear end of the pressing member 121 presses downward, and the pressing member 121 drives the pulling rib 127 to rotate clockwise, and the pulling rib acts on the front end of the container in the outer shell with an upward pulling force, and the pressing member 121 acts on the rear end of the container in the outer shell with a downward squeezing force during the pressing process, and finally achieves the rupture of the container 20. In this way, the pulling rib 127 is provided at the front end of the pressing member 121, and the outer shell 11 is driven to rotate together by the rotation of the pulling rib 127, so that the container 20 inside the outer shell 11 is pulled and squeezed, and then crushed.

[0179] Optionally, there are four pulling bars 127, which are wound around the outer shell 11 in sequence along the circumferential direction and arranged at intervals. The connecting end 1212 of the pressing piece 121 is connected to the four pulling bars 127 at the same time. The outer shell 11 is driven to rotate together by the rotation of the pulling bars 127, thereby pulling and squeezing the container 20 inside the outer shell 11, thereby achieving crushing.

[0180] Of course, longitudinal reinforcing ribs can also be set at the bottom of the front end of the shell 11. The longitudinal reinforcing ribs can ensure that the pulling ribs 127 further pull the shell 11 to the bottom of the shell 11 during the clockwise rotation, so as to squeeze the bottom of the container 20, thereby further ensuring the rupture of the container 20.

[0181] In this embodiment, the housing 11 , the pulling rod 127 and the pressing member 121 are integrally formed, thereby reducing the number of installation steps and saving time.

[0182] In this embodiment, the pressing structure 12 is provided with at least one second reinforcing rib 128. The second reinforcing rib 128 is provided on the side of the pressing member 121 facing the crushing member 122, and the second reinforcing rib 128 is spaced apart from the crushing member 122. Optionally, the second reinforcing rib 128 may be a strip reinforcing rib, and the second reinforcing rib 128 is provided on the inner side of the front end of the pressing member 121. The second reinforcing rib 128 may also be provided at any position of the crushing member 122, such as the front end, the rear end, the left side, and the right side. The second reinforcing rib 128 is conducive to allowing the crushing member 122 to swing back and forth during the crushing process, so as to facilitate the crushing of the container 20.

[0183] Optionally, a notch is formed at the connection position between the second reinforcing rib 128 and the crushing piece 122 to facilitate the crushing of the crushing piece 122 .

[0184] Please refer to Fig.18 The inner wall 111 of the housing 11 is provided with a crushing protrusion 116. The crushing protrusion 116 can further abut against the top and the bottom of the container 20 during the pressing process, so as to facilitate the crushing of the container 20.

[0185] Optionally, the crushing protrusion 116 is in the shape of a strip. There are two crushing protrusions 116, which are distributed above and below the inner wall 111 of the shell 11, wherein the two crushing protrusions 116 are symmetrically distributed in the up and down directions of the shell 11, so that the crushing protrusions 116 can abut against the same position of the top and bottom of the container 20 to achieve crushing during the pressing process.

[0186] Optionally, the crushing protrusion 116 is a V-shaped structure, and the crushing protrusion 116 is arranged along the vertical direction of the shell 11, which can help guide the shell 11 to deform along the vertical direction, thereby achieving more precise control. When the shell 11 is subjected to force, the crushing protrusion 116 can disperse the stress and avoid stress concentration.

[0187] Optionally, the connection position between the pressing piece 121 and the outer shell 11 is position W, and position W is spaced apart from the crushing protrusion 116 located above the inner wall 111 of the outer shell 11, so that during the pressing process, the crushing protrusion 116 can independently crush the surface of the container 20, and the pressing piece 121 can also squeeze the container 20, further effectively ensuring the crushing of the container 20.

[0188] Optionally, the size of the crushing protrusion 116 can be set larger, so that after the container 20 is installed in the container accommodating cavity 110, the crushing protrusion 116 leaves scratches on the surface of the container 20 by rotating the container 20, so that the subsequent crushing work is smoother.

[0189] It is also necessary to explain that please refer to Fig.19 The outer shell 11 includes an inner shell 102 and an outer shell 101. The inner shell 102 is telescopically arranged in the outer shell 101, so that the accommodating length of the container accommodating cavity 110 in the outer shell 11 can be adjusted to accommodate more containers 20 of different sizes.

[0190] The pressing member 121 of the pressing structure 12 is connected to the inner shell 102, and the pulling ribs 127 are connected to the pressing member 121, and the pulling ribs 127 are arranged around the inner shell 102. Optionally, the pressing member 121 of the pressing structure 12 is connected to the outer shell 101, and the pulling ribs 127 are connected to the pressing member 121, and the pulling ribs 127 are arranged around the outer shell 101. The outer shell 11 forms an inner and outer sleeve structure through the telescopic arrangement of the inner shell 102 and the outer shell 101, so that during the pressing process, the outer shell 11 is displaced in the front-to-back direction through the telescopic arrangement between the inner shell 102 and the outer shell 101, thereby adjusting the position on the outer shell 11 that needs to be deformed, so as to facilitate deformation, thereby facilitating breaking the container 20.

[0191] Of course, part of the outer shell 11 can be set as a bellows 103, so as to facilitate breaking the container 20 and rupturing it.

[0192] Please refer to Fig. 20 One end of the pressing structure 12 is connected to the housing 11, and the other end of the pressing structure 12 extends toward one end or the other end of the housing 11. In other words, the other end of the pressing structure 12 can extend toward the front end of the housing 11, or toward the far end of the housing 11.

[0193] It should be noted that the other end of the pressing structure 12 can form a horn structure when extending toward the front end of the shell 11, so that when pressed, the pressing structure 12 can be pressed against the desktop to reversely crush the container 20.

[0194] Please refer to Fig.21 In this embodiment, the pressing structure 12 cooperates with the housing 11 in the form of a flip cover. Optionally, the connection end 1212 of the pressing member 121 is connected to the housing 11, and the pressing member 121 can rotate around the connection end 1212, so as to flip relative to the housing 11. When pressing is required, the pressing member 121 is rotated counterclockwise around the end point of the connection end 1212, that is, rotated in the direction of F1 in the figure, so that the crushing member 122 reaches the top of the pressing hole 113, and the pressing end 1213 of the pressing member 121 is continuously pressed down, so that the crushing member 122 is inserted into the pressing hole 113, and directly acts on the surface of the container 20 in the container accommodating cavity 110, thereby achieving crushing.

[0195] In summary, the embodiment of the present invention provides an applicator 10, an application device 100 and an application kit 1000, the applicator 10 includes a shell 11 and a pressing structure 12, the shell 11 is formed with a container accommodating chamber 110, the container accommodating chamber 110 can accommodate at least two containers 20, the shell 11 is penetrated by a pressing hole 113, the pressing hole 113 is connected to the container accommodating chamber 110, the pressing structure 12 includes a connected pressing member 121 and a crushing member 122, the pressing member 121 and the shell 11 are movably connected, the pressing member 121 is used to drive the crushing member 122 through the pressing hole 113 under the action of an external force to directly act on the surface of the container 20, so that the crushing member 122 crushes the container 20, and the liquid in the container 20 flows out and reaches the smear cotton 182, so as to perform subsequent smearing work. When in use, the pressing structure 12 can directly act on the surface of the container 20, and can achieve that the container 20 can be crushed with a small force, which is more labor-saving to use.

[0196] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto.
